It doesn't matter anymore because I've partly resolved the problem, and 
it partly comes from portaudio...

If pa_process.c has been modified like explained in following link:

http://music.columbia.edu/pipermail/portaudio/2012-December/014649.html

audioindev audiooutdev can be forced before declaring asio like this:

pd -audioindev 13 -audiooutdev 12 -asio

Then It's possible to know which device to use with this command:

pd -audioindev 0 -audiooutdev 0 -asio -listdev

I hope someone can rewrite PaError pa_open_callback(...) in s_audio_pa.c 
because all those problems mainly comes from this function, and asio 
will certainly work better for everyone. My guess would be about making 
sure that p_instreamparams and p_outstreamparams aren't NULL before 
starting pa_stream.

cheers,
